IMPROVED APPARATUS FOR ROLLING RAILS.

Specification forming part of Letters Patent No. 68,936, dated September17, 1867.

To all whom it may concern:

Be it known that I, HUGH BAINES, of Manchester, in the county ofLancashire, England, have invented new andA useful Improvements inRolling-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference beinghad to the accompanyingdrawings, forming part of this specification.

The present invention relates more particularly to arolling-machineinvented by me, and secured by a grant of Letters Patentof the United States bearing date the-11th day of December, A. D. 1866.

The invention consists in a novel applica tion and arrangement ofrollers, t0 he now described, reference being had to the accompanyvingplate of drawings, in which- Figure l is a plan or top view of therollinginachine with the present improvements applied thereto, Fig. 2, atransverse vertical section taken in the plane of the line .r m, Fig. 1;Figs. 3 and 4, vertical sections taken, respectively, in the planes ofthe lines y y and z z, Fig. 1. f

Similar letters of reference indicate corresponding parts.

A A in the drawings represents the bed or foundation plate of themachine, having parallel uprights B B, between which two rollers, C C,are placed, the one above the other, and each turning in suitable blocksor bosses D, arranged in the uprights B. Bot-h rollers C C are madehollow7 through their entire length from end to end. Y

H H, gear-wheels at each end of rollers C, upon the inside of theuprights B, the gear- .wheels at the saine end of each rollerinterloekin g with each other. These gear-wheels H H are keyed to therollers, so as to turn in conjunction therewith, but yet allow of theireasy detachment from the same.

To the upper side of each of the uprights B is hunga weighted lever, gg, that rests through a pin, O, upon the journal-box or boss of theupper roller, C, the object of which weighted' levers is to hold theupper roller firmly down to its work, the weight upon each lever beingsusceptible of adjustment according to the .amount of pressure desired.

The arrangement of the parts above described, as well as areversiblegearing in connection with the lower roller of the .two rollers C C, isthe same as that described in the schedule annexed to the Letters Patenthereinbefore referred to, and therefore need no further or particulardescription herein.

The upper roller C of the two rollersG C is provided with a raised angeor roller, P,

the periphery or edge of which is grooved l suitably to roll the upperor bearing surface of a railroad-rail from a suitable metal bar whenpassed between itand the raisedflan'ge or roller Q, to the lower rollerof the two rollers C, which roller Q is fiat upon and around itsperiphery or edge.

R R and S S, four rollers, carried in boxes i T and U, respectively. Theone T `of these` boxes is fixed, and .the other arranged` so as to bemoved or slid upon the fixed bearings V, toward or away fromv the otherbox, when operated upon, by properly turning the calnlever cam W in theproper direction therefor.

These rollers R B and S S are forrolling the sides to a railroad-rail,and upon their periph cries are formed accordingly, `as' is apparentfrom an inspection of the Figs. 3 and 4 of the in motion, at the sametime bringing the sideV rollers into position through the cam-lever,forging the metal to the required-size.

In cases where the metal is heated from one end or all over, thecam-lever and fiat place ou roller or flange I? are not employed.

I claim as new and desire to secureby Letters Patent-- The rollers P, Q,B, and S, in combination with each other, .when constructed and arrangedtogether substantially as and for the purpose described. The abovespecification of lny invention signed by me this 3d day of July, 1867.

- i HUGH BAINES.
